Abstract
Pulsed twin-arc welding features separate feed of current pulses to electrically insulated consumable electrodes, the arcs of which form a common weld pool. This results in a relatively high (up to 30 kg/h) coefficient of electrode wire melting, high (up to 120 m/h) welding speed, and favourable butt and fillet weld formation. Prospects for further development of the tandem-arc welding processes are outlined.
Keywords: twin-arc welding, current pulses, synergic control, shielding gases, power sources, welding modes, weld formation, welded joint properties
